The Livonian crusade consisted of the various military Christianisation campaigns in medieval Livonia – modern Latvia and Estonia – during the Papal-sanctioned Northern Crusades in the 12th–13th century.
Overview
Historical sources
The main source of information on the Livonian crusade is the Livonian Chronicle of Henry, written in c. 1229 by Henry of Latvia (Henricus de Lettis). In his chronicle, the author notes that he penned it down at the urging of his lords and companions, including his former teacher bishop Albert of Riga, who receives much praise throughout the text, that is internally divided according to the years of Albert's episcopate. James A. Brundage (1972) posited that Albert commissioned Henry to write the Livonian Chronicle in the mid-1220s in order to glorify Albert's achievements, as well as to briefly summarise unresolved issues to the newly appointed papal legate, William of Modena.
Henry wrote that the papacy's use of the crusade as a foreign policy was extended to include military expeditions against the Livonians for the first time by papal proclamation in c. 1195, and then renewed in 1197 or 1198. There are no independent sources to confirm this; the earliest surviving papal letter on the Livonian crusade dates from 5 October 1199, issued by Pope Innocent III. Most surviving documents relating to William of Modena's mission as legate deal with problems caused by rivalries and internal tensions within the Catholic Church in Livonia and neighbouring areas. There are only scattered references to his interactions with converted populations in the Baltic, and no traces of William interacting with representatives of Novgorod, Pskov, Jersika, or non-Christian powers in the region. When he returned to Rome in 1226, the Apostolic Chancery in Rome issued a series of letters and decrees on affairs in Livonia, far more detailed than any previous papal communications on the Baltic, that were very vague and showed little interest in the region.
Participants
The 1199 letter of Innocent III provided that Christians who had vowed to go on pilgrimage to the Holy Land would receive an indulgence (or commutation) of penance for sins if they chose to participate in the Livonian crusade instead, and that they would receive the right to papal protection if they did. Participants would be wearing the insignia of the cross, which came with specific legal obligations; unlike crusaders in the Holy Land, it meant that the wearer had to serve in the papally proclaimed crusade in Livonia for at least one year.
Organisation
Unlike previous crusading enterprises that were usually started by the pope, Albert of Buxhoeveden, bishop of Riga, appears to have been the primary initiator and recruiter for the Livonian crusade. Moreover, it was initially not accompanied by a papal legate either until 1224, some three decades after the crusade's launch. In previous crusades, papal legates would always represent the pope, frequently preach to the crusaders, take part in military action, and serve a diplomatic role as the pope's spokesman on political and spiritual policies. When William of Modena was finally appointed legate in late 1224, it was at the request of Albert of Riga rather than by the pope's own initiative. Overseeing the crusading operation might not even have been a (great) part of William's mission, as it is not mentioned explicitly in his mandate. Brundage (1972) argued that from the mid-1220s, the papacy seemed to take a more active interest in the Livonian crusade, especially by combining the military objective of conquest with the religious objective of conversion of the subjected populations. In previous examples, such as the 1147 Wendish Crusade, conquest and proselytisation were more or less separate activities, without close cooperation between crusaders and missionaries.
Geography
The Livonian crusade was conducted mostly by the Holy Roman Empire and the Kingdom of Denmark. It ended with the creation of Terra Mariana and the Danish duchy of Estonia. The lands on the eastern shores of the Baltic Sea were one of the last parts of Europe to be Christianised.
On 2 February 1207, in the territories conquered, an ecclesiastical state called Terra Mariana was established as a principality of the Holy Roman Empire, and proclaimed by Pope Innocent III in 1215 as a subject of the Holy See. After the success of the crusade, the Teutonic- and Danish-occupied territory was divided into six feudal principalities by William of Modena.
Wars against Livs and Latgalians (1198–1209)
By the time German traders began to arrive in the second half of the 12th century to trade along the ancient trade route from the Varangians to the Greeks, some natives had already been baptized.
Saint Meinhard of Segeberg arrived in Ikšķile in 1184 with the mission of converting the pagan Livonians, and was consecrated as Bishop of Üxküll in 1186. In those days the riverside town was the center of the missionary activities in the Livonian area.
The indigenous Livonians (Līvi), who had been paying tribute to the East Slavic Principality of Polotsk, and were often under attack by their southern neighbours the Semigallians, at first considered the Low Germans (Saxons) to be useful allies. The first prominent Livonian to be converted was their leader Caupo of Turaida, who was baptized around 1189.
Pope Celestine III had called for a crusade against pagans in Northern Europe in 1193. When peaceful means of conversion failed to produce results, the impatient Meinhard plotted to convert Livonians forcibly but was thwarted. He died in 1196, having failed in his mission. His appointed replacement, bishop Berthold of Hanover, a Cistercian abbot of Loccum arrived with a large contingent of crusaders in 1198. Shortly afterwards, while riding ahead of his troops in battle, Berthold was surrounded and killed, and his forces were defeated by Livonians.
To avenge Berthold's defeat, Pope Innocent III issued a bull declaring a crusade against the Livonians. Albert von Buxthoeven, consecrated as a bishop in 1199,
arrived the following year with a large force, and established Riga as the seat of his Bishopric of Riga in 1201. In 1202, he formed the Livonian Brothers of the Sword to aid in the conversion of the pagans to Christianity and, more importantly, to protect German trade and secure German control over commerce.
As the German grip tightened, the Livonians and their christened chief rebelled against the crusaders. Caupo's forces were defeated at Turaida in 1206, and the Livonians were declared to be converted. Caupo subsequently remained an ally of the crusaders until his death in the Battle of St. Matthew's Day in 1217.
By 1208 the important Daugava trading posts of Salaspils (Holme), Koknese (Kokenhusen) and Sēlpils Castle (Selburg) had been taken over as a result of Albert's energetic campaigning. In the same year, the rulers of the Latgalian counties Tālava, Satekle, and Autine established military alliances with the Order, and construction began on both Cēsis Castle and a stone Koknese Castle, where the Daugava and Pērse rivers meet, replacing the wooden castle of Latgalians.
In 1209 Albert, leading the forces of the Order, captured the capital of the Latgalian Principality of Jersika, and took the wife of the ruler Visvaldis captive. Visvaldis was forced to submit his kingdom to Albert as a grant to the Archbishopric of Riga, and received back a portion of it as a fief. Tālava, weakened in wars with Estonians and Russians, became a vassal state of the Archbishopric of Riga in 1214, and in 1224 was finally divided between the Archbishopric and the Order.
Wars against Estonians (1208–27)
Conquest of the Estonian hinterland
By 1208 the Crusaders were strong enough to begin operations against the Estonians, who were at that time divided into eight major and seven smaller Counties, led by elders, with limited co-operation between them. With the help of the newly converted local tribes of Livs and Latgalians, the crusaders initiated raids into Sakala and Ugaunia in Southern Estonia. The Estonian tribes fiercely resisted the attacks from Riga and occasionally sacked territories controlled by the crusaders.
In 1208–27, war parties of the different sides rampaged through Livonia, Latgalia, and other Estonian counties, with the Livs, Latgalians and Russians of the Republic of Novgorod serving variously as allies of both crusaders and Estonians. Hill forts, which were the key centers of Estonian counties, were besieged, captured, and re-captured a number of times. A truce between the war-weary sides was established for three years (1213–1215). It proved generally more favourable to the Germans, who consolidated their political position, while the Estonians were unable to develop their system of loose alliances into a centralised state. They were led by Lembitu of Lehola, the elder of Sackalia, who by 1211 had come to the attention of German chroniclers as the central figure of the Estonian resistance. The Livonian leader Caupo was killed in the Battle of St. Matthew's Day near Viljandi (Fellin) on 21 September 1217, but Lembitu was also killed, and the battle was a crushing defeat for the Estonians.
The Christian kingdoms of Denmark and Sweden were also eager for expansion on the eastern shores of the Baltic. In 1218 Albert asked King Valdemar II of Denmark for assistance, but Valdemar instead arranged a deal with the Order. The king was victorious in the Battle of Lindanise in Revelia in 1219, to which the origin of the Flag of Denmark is attributed. He subsequently founded the fortress Castrum Danorum, which was unsuccessfully besieged by the Estonians in 1220 and 1223. King John I of Sweden tried to establish a Swedish presence in the province of Wiek, but his troops were defeated by the Oeselians in the Battle of Lihula in 1220. Revelia, Harrien, and Vironia, the whole of northern Estonia, fell to Danish control.
During the uprising of 1223, all Christian strongholds in Estonia save Tallinn fell into Estonian hands, with their defenders killed. By 1224 all of the larger fortresses were reconquered by the crusaders, except for Tharbata, which was defended by a determined Estonian garrison and 200 Russian mercenaries. The leader of the Russian troops was Vyachko, to whom the Novgorod Republic had promised the fortress and its surrounding lands "if he could conquer them for himself". Tharbata was finally captured by the crusaders in August 1224 and all its defenders were killed.
Early in 1224 Emperor Frederick II had announced at Catania that Livonia, Prussia, Sambia and a number of neighboring provinces would henceforth be considered reichsfrei, that is, subordinate directly to the Roman Catholic Church and the Holy Roman Empire only, as opposed to being under the jurisdiction of local rulers. At the end of the year Pope Honorius III announced the appointment of Bishop William of Modena as papal legate for Livonia, Prussia, and other countries.
In 1224 the Livonian Brothers of the Sword established their headquarters at Fellin (Viljandi) in Sackalia, where the walls of the Master's castle are still standing. Other strongholds included Wenden (Cēsis), Segewold (Sigulda), and Ascheraden (Aizkraukle).
The Chronicle of Henry of Livonia, one of the greatest medieval narratives, was written probably as a report for William of Modena, giving him the history of the Church in Livonia up to his time. It relates how in 1226, in the stronghold Tarwanpe, William of Modena successfully mediated a peace between the Germans, the Danes and the Vironians.
War against Saaremaa (1206–61)
The last Estonian county to hold out against the invaders was the island country of Saaremaa (Ösel), whose war fleets had continued to raid Denmark and Sweden during the years of fighting against the German crusaders.
